NAME
       logsave - save the output of a command in a logfile

SYNOPSIS
       logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION
       The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its out‐
       put  to logfile.	 If the containing directory for logfile does not exist, logsave will accumulate the
       output in memory until it can be written out.  A copy of the output will also be written to  standard
       output.

       If  cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its in‐
       put from standard input and save it in logfile

       logsave is useful for saving the output of initial boot scripts until the /var partition is  mounted,
       so the output can be written to /var/log.

OPTIONS
       -a     This  option will cause the output to be appended to logfile, instead of replacing its current
	      contents.

       -s     This option will cause logsave to skip writing to the log file text which is bracketed with  a
	      control-A (ASCII 001 or Start of Header) and control-B (ASCII 002 or Start of Text).  This al‐
	      lows  progress bar information to be visible to the user on the console, while not being writ‐
	      ten to the log file.

       -v     This option will make logsave to be more verbose in its output to the user.
